Are prediction markets easy to manipulate?
Basically there are two types of manipulations: • Users are trying to gain more money and get better rankings with illegal actions. • Users are trying to manipulate values of shares at the cost of making personal losses. The way political prediction markets are working makes it impossible to manipulate values of shares in the long run. We could prove in past projects that values of shares have a very high resistance against these kinds of ma-nipulations and that it was not possible for the user to change values in the long run. As pro:kons projects are running since 1999 we have developed a variety of security mechanisms to prevent and detect manipulations at an early stage.
